Title: Pyroelectric infrared sensor
Inventor: MIKI KATSUMASA
IPC: G01J1/04
Filed: 1994-04-26
Abstract: PURPOSE:To improve stability and reliability in driving a small chopper of a pyroelectric infrared sensor using a piezoelectric actuator. CONSTITUTION:Piezoelectric bodies 12a and 12b are bonded to shims 11a and 11b, respectively, and only a fixing part hole 21a at one end of the shin 11a is fixed with a sensor pedestal 14 and an unimorph element fixture 15a, thus a unimorph piezoelectric element is constituted. Since resonance frequency of a unimorph element is lowered so that a chopper drives at the frequency lower than resonance frequency by about 10%, displacement can be enlarged without using the resonance point whose displacement is unstable, so, the sensor is miniaturized, and adjustment of resonance frequency becomes easier, and rigidity in the direction other than the vibration direction is raised due to multiple supporting paints, thus, more stable driving is realized.

Abstract: PURPOSE: To obtain a separate plate for the control valve in an automatic transmission capable of obtaining excellent sealability regardless of the surface properties or rigidity of a seal surface by providing a seal part composed of a foamed rubber layer with specific thickness to the single surface or both surfaces of a metal plate. CONSTITUTION: A separate plate 1 is constituted by forming a seal part 3 to the single surface or both surfaces of a metal plate 2 and providing through- holes 4 corresponding to oil passages to the metal plate by punching. The seal part 3 is formed from a foamed rubber layer with a thickness of 80-500μm.
